Unique Driving Characteristics

The system helps reduce fuel consumption by automatically shutting off and restarting the engine while your vehicle is stopped. The engine will restart automatically when you release the brake pedal. In some situations, your vehicle may restart automatically, for example:

• To maintain interior comfort

• To recharge the battery

Note: Power assist steering is turned off when the engine is off.

WARNING: Always fully apply the parking brake. Failure to follow this instruction could result in personal injury or death.

WARNING: Apply the parking brake, shift into park (P), switch the ignition off and remove the key before you leave your vehicle. Failure to follow this instruction could result in personal injury or death.

WARNING: The system may require the engine to automatically restart when the auto-start-stop indicator illuminates green or flashes amber. Failure to follow this instruction could result in personal injury.

The Auto-Start-Stop system status is available at a glance within the information display. See Information Displays (page 97).

The system is automatically enabled every time you start your vehicle if the following conditions are met:

• The Auto-Start-Stop button is not pressed (not illuminated).

• Ambient temperature is moderate.

The green Auto-Start-Stop indicator light on the instrument cluster will illuminate to indicate

when the automatic engine stop occurs.

If the instrument cluster is equipped with a grey

Auto-Start-Stop indicator light, it is illuminated when automatic engine stop is not available due to one of the above noted conditions not being met.

Any of the following conditions will result in an automatic restart of the engine:

Press the Auto-Start-Stop button located on the center console to switch the system off.

The button will illuminate. The system will only be deactivated for the current ignition cycle. Press the button again to restore Auto-Start-Stop function.

If your vehicle is in an Auto-Start-Stop state and you shift the transmission to reverse without pressing the brake, a message telling you to press the brake appears. You must press the brake pedal within 60 seconds, or you will need to shift to park and manually restart your vehicle.
